My domain has:
2 Domain controllers (windows 2003), which are also internal dns servers. (Internal IP .123 &124)
1 of these DCs is a DHCP server. DHCP hands out 123 & .124 for DNS.
How can I tell what DNS IP external requests are going to? I know we have our private DNS through our ISP, but need to confirm the exact IP. Is this configured in the firewall (Cisco ASA)?
